  1. DIY Speakers and Subs
    I'm building the tower version of "Dr. K's MTM" and I don't know how much lining I should put in. Also, I'm using old memory foam from a mattress, I figure it is dense enough and stable enough not to break down and crumble over the years. If there's any reason I should not be using memory...
  2. Audio Theory, Setup, and Chat
    Since Vicoustic discontinued their original Wavewood panel for the “Lite” version, I set to work creating my own. I got a CAD drawing of the original MLS slot pattern and sent it to a woodworking company to cut and finish. I then sourced the same density foam as the original, but twice as...

    Hi! I'm starting this thread in hopes of getting answers to several questions I have, regarding setup, acoustic treatment, optimal placement, suggestions for hifi equipment.

    Intro I’m reaching out to the group for pre-construction advice on front wall sound absorption. My concern centers on planned use of di-pole side surround speakers with tweeters angled front and rear at about a 30 degree angle (that’s a guess from looking at them). I’ve read hours of posts on...
  7. Audio Gear
    5 tube traps I built to tame the bass frequency of my room. Like the ASC traps, have of their surface is lined with a sheet of plastic lining, to keep mid and high frequencies from getting absorbed. Built from fiberglass pipe fittings, with oak end pieces to seal them. Works great for handling...
